i guess this really goes without mentioning..but just in case…DO NOT FORGET TO BRING IN DA CRITTERS on these FREEZING NIGHTS! and unless you include their space with the forced air heating…it wouldnt hurt to give em another blanket or something. if your pet sleeps with you, then you might expect to feel a cold nose under the blankets as the weather gets colder. dont kick em out unless you tuck them in with more warmth.
